1. Preparation

Gather the necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery to ensure safety while working.

2. Drain Transmission Fluid

Locate the transmission fluid drain plug.
Use a socket set to remove the drain plug and allow the fluid to completely drain into a suitable container.
Replace the drain plug and torque to manufacturer specifications.

3. Remove the CVT Belt Cover

Remove any components obstructing access to the CVT belt cover (e.g., splash shield).
Use a socket set to remove the bolts securing the CVT belt cover.
Carefully lift the cover off and set it aside.

4. Inspect and Replace the CVT Belt

Examine the CVT belt for signs of wear, cracks, or glazing.
If replacement is necessary, note the belt routing and carefully remove the old belt from the pulleys.
Install the new CVT belt, ensuring it is properly seated in the pulleys and follows the correct routing.

5. Reassemble and Refill Fluid

Reattach the CVT belt cover and secure it with the bolts.
Refill the transmission with manufacturer-approved CVT fluid through the fill plug.
Check fluid level using the dipstick and add more fluid if necessary.

6. Reconnect Battery and Test Drive

Reconnect the battery.
Start the engine and allow it to reach operating temperature.
Test drive the vehicle to ensure proper functionality of the CVT system and check for any unusual noises or symptoms.
